Perhaps you should try some spelling variations:
"and computational in computer program" » "_ computational in computer program" (Expand search), "and computational and computer program" (Expand search), "and computational _ computer program" (Expand search), "and computational 3d computer program" (Expand search)
"using computation _ python programming" » "using computational _ python programming" (Expand search), "using imputation _ python programming" (Expand search), "using compilation _ python programming" (Expand search)

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"and computational in computer program\") OR (\"using computation _ python programming\"))~".
• Removing quotes may allow a broader search: (( and computational in computer program ) OR ( using computation _ python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("and computational in computer program") OR ("using computation _ python programming"))*.
